Yep, agree with you on that. Just how they were geniuses, don't you think there are regular people who are capable of being extremely successful despite of attending mediocre schools? My example was to show that it all comes down to intelligence, doesn't it? So then why the need to have a label of ivy league to prove to the world that you got brains. Why is it so hard for some people to get beyond that mentality?
What you said about business is also true, in the business field you need a good network and all to be at the top of the game which comes from a good school.. but does that mean an average business graduate cannot have a successful career?
of course, they can. anyone who works hard enough can succeed regardless of a degree or not.
the only point I think is that certain opportunities are restricted to the top schools. for example, it's much harder/impossible to get into top finance jobs unless you got to a top school. this is why ppl say that an MBA is only worth getting if you got to a top 10 school. but then again things depend a lot on your personal situation, your goals, your location, etc.
I think we're all saying the same thing. just looking at it from different angles.
